Detailed Description
The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1 to 3, a bracket pressing and fixing device includes a connection base 10 and an upper cover 20, wherein the connection base 10 and the upper cover 20 are both made of aluminum, so that the bracket pressing and fixing device is convenient to process and suitable for mass production.
The upper end face of the connecting base 10 is provided with a conical boss 11, the center of the conical boss 11 is provided with a sinking groove 12, the center of the sinking groove 12 is provided with a first connecting hole 13, and the two sides of the first connecting hole 13 are symmetrically provided with second connecting holes 14. Wherein, this first connecting hole 13 is threaded connection hole, and second connecting hole 14 is the counter sink, and first connecting hole 13 is used for with plum blossom handle screw one end threaded connection, and second connecting hole 14 is used for passing through second connection 14 holes through the screw, will connect base 10 and shot-light bulk phase and be connected.
The lower end surface of the upper cover 20 is provided with a tapered connecting groove 21 matched with the tapered boss 11, the center of the tapered connecting groove 21 is provided with a third connecting hole 22 concentrically arranged with the first connecting hole 13, and both sides of the third connecting hole 22 are provided with fourth connecting holes 23 concentrically arranged with the second connecting hole 14.
